From the company’s statement:

Greystripe is the first company to offer ad-supported mobile games worldwide via its online and mobile gaming portal GameJump.com and through its AdWRAP Catalog program. Greystripe’s mobile gaming network includes 800 free mobile games from 70 publishers with more than seven million games downloaded since its launch less than one year ago.

Its patent-pending AdWRAP technology provides an automated process to enable advertisements to be wrapped directly with mobile games and applications without any complex coding and development for the content owner. AdWRAP provides both game publishers and carriers an additional source of revenue, while simultaneously building customer retention and loyalty.

The latest round brings Greystripe’s total funding to $10.1 million. Existing investors, Monitor Ventures and Incubic Venture Capital, also participated in the latest round.
